I didn't discover this until yesterday, but you can select from thousands of music videos at Yahoo music. For free.
Their marketing plan is an interesting one. In exchange for loading and running a 30-second commercial that you cannot fast-forward or skip, you get to see the video.
You may think wow what a deal, but keep in mind that back when MTV and VH1 actually played music, the ratio was three or four videos per commercial break, not one to one. So maybe a little bit of a step backwards, though at least you get to choose the video yourself, and don't have to endure gangsta misogyny or pop-tart banality before finally getting to the good stuff (unless the commercial is a promo for their latest...shudder).
So I've gone through and seen some of the old favorites. As an iPod man, Metallica is of course going around the top of the list. Some offerings have proven disappointing with more exposure. Metallica's "Fuel" is not the rush I remember, and Hole's "Celebrity Skin" is downright boring. Glad I never bought that album.
But "Head Like a Hole" surprisingly weathers the test of time. And Pearl Jam's disturbing "Do the Evolution" is fascinating in a sickening sort of way. Anything by R.E.M. is good, too.
Check out the service, but don't indulge too much. Those videos dull the mind when watched with profusion.
(Trent Reznor is an awfully good musician. I wish he would write tunes that are not so ugly and depressing.)
